WASHING-MACHINE.

Specification of Letters Patent. I Patented July 28, 1914:-

Application filed April 1, 1914. Serial No. 828,705.

To all whom it may concern:

Beit known that I, AARON Kn'ro, a citizen of Finland, residing at F itchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

This invention relates to improvements in washing machines and more particularly to devices of this class that can also be used as churns or for similar purposes where agitation of a liquid by means of a rotary drum is desired.

My invention contemplates an outer r0- tary drum and an inner rotary drum carried thereby, the walls of the inner rotary drum being reversible to prevent contamination of the contents of the inner drum by any residue from matter previously contained therein.

WVith the foregoing and other objects in view the inventionconsists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claims and illustrated in the accompanying drawings which form a part of said specification and in which 2- Figure 1 is a front elevation of my improved washing machine. I Fig. 2 is a section taken on line 2-2 of Fig. 1. Fig. 3 is an end elevation of the device with a portion of the outer drum and the inner drum shown 'in section. Fig. 4 is a section taken on line ll of Fig. 1. Fig. 5 is a section taken on line 55 of Fig. 1.

Like reference characters indicate corresponding parts throughout the several views.

My machine comprises a frame 1 provided castings 6, 6 through which the threaded.

stem 7 of a hand wheel 8 extends and which stem upon its inner extremity carries a clamp 9 adapted to grip one corner of the inner drum 10, also square in cross section. Two opposite sides of the drum 10 are proand in said'frame trunnions 3, 3

vided with marginal pins 11 which extend through said sides and upon which the remaining sides of the drum obtain a-bearing; the four sides'of the drumbeing so fitted together as to be water tight. The constructlon of the inner drum is such that its walls can'be individually removed and inverted so that when the machine has been used as a washing machine the several walls can be inverted to permit its use as a churn. The outer drum is provided with a hand-controlled clamping member 12 which extends through its wall and is provided with ahead 13 adapted for frictional engagement with the inner drum to further secure the same in adjustedposition with relation to the outer drum. The outer drum, moreover, is provided with a sliding wall B which serves as a cover and access to the interior of the inner drum is to be had by removing one of its four walls. A drain pipe 14 serves to withdraw the contents of the machine when desired.

What is claimed is 1. Ina washingmachine, an outer rotary drum, square incross section, mounted in a frame and provided with an operating handle, an inner rotary drum, square 1n cross section, formed wlth reverslble walls,

clamping means releasably securing said drums together inner drum.

2. In au washing machine, drum, squarein cross section, mounted in aframe and provided with an operating and a drain pipe for said handle, an inner rotary drum, square in cross section, formed with removable walls, marginal pins carried by one palr of oppoan outer rotary.

site walls as bearings for the remaining pair of walls, clamping means for releasably securing sa dawalls in operative relation and for releasably securing sald drums together I and a drain pipe for said innerdrum.

In testimony that I claim the as my own Ihave hereto aflixed foregoing my signa-v ture in the presence of two subscribing wit- HGSSBS.
